Abstract
A disposable substantially dry foamable product is described including a water-insoluble substrate such as a flexible web, the substrate having first and second major surfaces, with a plurality of moguls spaced apart on the first major surface and a foamable composition deposited in major amounts on the second surface and a minor amount on the first surface. A method for producing the product is also described which employs the moguls in juxtaposition to a guide roller to establish space between a surface of the roller and the first surface of the substrate. Foamed composition is deposited onto the second surface which by seepage through apertures in the substrate allow a minor portion of the coating composition to deposit on the first surface of the substrate.
